'South Park': 15 shocking moments

In 15 seasons on the air (the 16th season began Wednesday), Trey Parker and Matt Stone have found a way to skewer just about every race, religion, interest group and orifice. They've taken on sacred cows and wallowed in cheap laughs. Surprisingly, a lot of times the groups involved weren't offended. In fact, the show has won Emmys, a Peabody and been nominated for a GLAAD award. But not everyone can take a joke, and sometimes the boys from Colorado manage to shock and offend just about everyone. Here are some of the most outrageous moments from their first 15 seasons.

Air date: Nov. 16, 2005 The shock: It's heavily implied that actor Tom Cruise is a closeted gay man by having him hide in a closet while the characters constantly call: "Come out of the closet." The reaction: Cruise was reportedly unhappy with the episode, and when a rebroadcast was pulled from the Comedy Central schedule, Parker and Stone suspected pressure from the actor or Scientology to be involved. However, Cruise has since denied any knowledge of the incident. Actor Isaac Hayes was offended by the treatment of Scientology in the episode and quit the show in protest.
